Comment 3 for bug 627291

Andres, I'm not aware of any package that uses this at this point, but the missing pkg-config file is keeping me from building clusternet on ubuntu.

Try this:
git clone git://github.com/fabbione/clusternet.git
cd clusternet
./autogen.sh
./configure

and then you get:

checking for logt... configure: error: Package requirements (liblogthread) were not met:
No package 'liblogthread' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables logt_CFLAGS
and logt_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

liblogthread-dev is of course installed, it's just missing the appropriate .pc file.
